Question

The circuit shown in the figure below is connected for 2.50 min. (Assume R1 = 7.70 ?, R2 = 2.60 ?, and V = 10.0 V.)

(a) Determine the current in each branch of the circuit.


(b) Find the energy delivered by each battery.


(c) Find the energy delivered to each resistor.


(d) Identify the type of energy storage transformation that occurs in the operation of the circuit.

branch magnitude (A) direction left branch ? 2---Select---updown middle branch ? 4---Select---updown right branch ? 6---Select---updown 5.00 3.00 1.00 (2 4.00 V

Explanation / Answer

a) I) middle = 4/6 = 0.67 A up

I ) right = 10/5.6 = 1.79 A up

so I) left = 1.79 + 0.67 = 2.46 A down

c) energy delivered to resistors = i2 R

So 7.7 ohm = 46.6 J

5 OHM = 2.24J

1 OHM = 0.45 J

3 OHM = 9.61J

2.6 OHM = 8.33J
